Targeted Compression Garment Structure for Lymphoedema Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression garments for lymphoedema treatment lack effectiveness in providing sufficient strength and support in key areas such as the genitals, pubis, and groin, leading to inadequate lymphatic drainage.
Innovation Solution
A compression and contention garment with a main body made of a compression textile having an elasticity greater than 70% in one direction, reinforced with a layer of reinforcement textile in targeted areas and stiffened with a contention textile in specific zones, enhancing support and pressure application to facilitate lymphatic drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a compression garment uses uniform compression textile throughout, then the garment provides basic compression coverage, but it lacks sufficient strength and support in key edema localization areas such as genitals, pubis and groin
Solution Approach 1:
The patent applies local quality by incorporating reinforcement textile layers specifically in targeted areas (genitals, pubis, groin) where edema localization occurs, rather than uniformly throughout the entire garment. This allows the garment to provide enhanced strength and support precisely where needed while maintaining simpler construction in non-critical areas, thus resolving the contradiction between localized strength enhancement and overall structural complexity.
Solution Approach 2:
The patent uses composite materials by combining compression textile with reinforcement textile layers in specific zones. The reinforcement textile has different mechanical properties (higher strength and stiffness) than the base compression textile, creating a composite structure that optimizes both support in critical areas and overall garment flexibility, thereby addressing the strength-complexity contradiction.
2Adaptability or versatility
If the garment uses high elasticity compression textile, then the garment adapts to body morphology, but it provides insufficient rigidity and support in targeted areas
Solution Approach 1:
The patent resolves this contradiction by applying local quality through spatially differentiated material properties: the compression textile with high elasticity (>70%) provides adaptability to body contours in general areas, while reinforcement textile layers with higher stiffness are strategically placed in targeted areas (genitals, pubis, groin) to provide the necessary rigidity and support, thus achieving both adaptability and localized strength.
Solution Approach 2:
The composite structure combines compression textile (high elasticity for adaptability) with reinforcement textile (higher stiffness for support) in a layered configuration. This composite approach allows the garment to simultaneously achieve morphological adaptation through the elastic base layer and provide structural support in critical zones through the reinforcement layers, resolving the adaptability-strength contradiction.
3Force
If the garment applies uniform pressure throughout, then the garment is simple to manufacture, but it fails to apply significant force in specific locations where strong pressure is needed for effective drainage
Solution Approach 1:
The patent applies local quality by concentrating reinforcement textile layers in specific targeted areas (genitals, pubis, groin) where strong pressure is needed for effective lymphatic drainage, rather than distributing reinforcement uniformly throughout the garment. This localized approach achieves high pressure force in critical zones while minimizing additional manufacturing complexity compared to uniform reinforcement.
Solution Approach 2:
The garment is segmented into different functional zones: areas requiring high pressure (with reinforcement textile layers) and areas requiring standard compression (with base compression textile only). This segmentation allows the manufacturing process to focus reinforcement materials only where clinically necessary, balancing the need for targeted high force with manufacturing efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The garment effectively supports and drains swollen areas by adapting to the body's morphology, providing targeted rigidity and pressure to enhance lymphatic drainage, improving treatment efficacy.
Implementation Method 1
the compression textile having an elasticity strictly greater than 70% in at least one direction of extensibility
Implementation Method 2
the garment comprises at least one layer of reinforcement textile in the first targeted area, the garment having a module greater than the module of the compression textile in the first targeted area
Implementation Method 3
the contention textile having a stiffness, in at least one direction of interest, greater than or equal to 30 N/(m*mm) over any normal range of use of the garment
